Get your fishing gear at Wyatt's or one of the hardware stores in Meeker, or there's also a Walmart in Rifle.  Of course, fly fishing gear for the river is perfect, but casting tackle with a bright Mepps is great for Lake Avery. Be sure to review the Fishing regulations for Colorado.  There are no special restriction for Lake Avery (sometimes referred to as Little Beaver Reservoir).  In the winter, ice fishing on Lake Avery is also very popular.
